EMERGENCY AXLE AND WHEEL.

Specification of Letters Patent.

Patented Mar. as, rear.

Application filed March 2, 1920. Serial No. 362,676.

T 0 all whom it may concern:

Be it known that I, IVER J. Hnnsn'rH, a citizen of the United States, residin at Madison, in the county of Lake and tate of South Dakota, have invented certain new and useful Improvements in Emergency Axles and Wheels, of which the following is a specification.

This invention relates to attachments for automobiles and has for its object the provision of an emergency axle adapted to be clamped upon either the rear axle housing or the front axle of an automobile and carrying a wheel adapted to take the place of a missing ordinary wheel whereby the automobile may be towed or driven to the garage or other place where the necessary repairs may be made; the advantage of the device being that it eliminates the necessity for the employment of the trucks commonly used in connection with a broken axle.

An important object is the provision of a device of this character in which the auxiliary wheel is journaled upon a spindle projecting from a spindle body which is rotatable and with which is connected a rod adapted for connection with the steering arm connecting rod, when the device is used on the front axle, so that the auxiliary wheel may be moved simultaneously with the remaining front wheel so that the automobile may be steered in 'theordinary manner, this rod connected with the spindle body being also capable of being secured to a stub projection from the body of the device whereby the auxiliary wheel may be held against horizontal turning movement.

An'additional object is the provision of a device of this character which will be simple and inexpensive in manufacture, which may be quickly and easily applied, which will remain firmly in position, which will be ellicient and durable in service. and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings in which Figure 1 is a rear elevation of one end of a rear axle housing showing my device in position thereon,

Fig. 2 is a plan view thereof,

Fig. 3 is a plan view of the device showing associated with a broken front axle,

F 1g. 4 is a cross sectional view on the line 14 of Fig. 1, and

Fig. 5 is a cross sectional view on the line of F 1g. 1, with the clamping member shown swung into open position.

Referring more particularly to the drawings. the letter A designates the rear axle housing of an automobile and B designates the enlarged flange like portion at the outer end thereofagainst which the rear wheel is disposed. The rear spindle is indicated at c and is shown as broken off. D designates the front axle, also shown as broken oiit', and E the steering arm connecting rod.

In carrying out my invention I provide a bar 10 which is disposable beneath either the rear axle housing or the front axle and which is formed intermediate its ends with a downwardly offset portion 11. At one end the bar 10 is extended upwardly and formed with vertically spaced arms 12 between which is journally mounted a spindle body 13 from which projects a spindle 14 carrying a wheel 15 of the same size as the regular wheels of the automobile and equipped with a tire. Projecting from the spindle body is a arm 16 and projecting from the opposite end of the bar at one side thereof is a stub 17 Pivoted upon the end of the arm 16 is a U shaped yoke 18 through the bight portion of which is threaded one end of a rod 19 which carries a lock nut 20 engaging against the yoke. Pivoted upon the free end of the rod 19 is' a clamping member formed of two similar plates 21 provided upon their confronting faces with grooves 22 and through which passes a clamping bolt 23. These plates are capable of being clamped upon the stub 1'? as shown in Figs. 1 and 2 for hold ing the spindle body 13 rigid. Owing to the fact that the rod 19 is threaded into the yoke 18 it will be seen that adjustment may be made to vary the position of the wheel 15 so that it may be parallelized with respect to the other wheels of the automobile when my device is applied as will be hereinafter described.

Formed upon the upper side of the bar at its other endis a transverse portion 24 having a curved recess 25 forming a saddle. One end of this portion 24 is bifurcated to provide ears 26 between which is pivoted a bolt 27 carrying a handled nut 28. The other end of the portion 24: is formed with a hole 29. Associated with this portion 24. is a clamping member 30 which is formed at one end with a bifurcation within which is pivoted one end of a bolt 51 extending through the hole 29 and carrying a nut 32. The other end of the clamping member 30 bifurcated for the reception of the bolt 27. The clamping member 30 is also provided with a curved recess mating with the recess 25 to receive an axle of the automobile. Located adjacent the offset portion 11 of the bar is a saddle member 341- from'which depends a bolt 35 passing tirough. the bar 10 and carrying therebelow a nut 36. By this means the saddle member is rotatable upon the bar but may be secured in adjusted position. The member 34- is provided with a curved recess 37 and has one end formed bifurcated to define ears 38 and its other end formed with a hole 39. Pivoted between the ears 38 is a bolt 10 carrying a handled nut 41. Associated with the saddle member 3t isa clamping member 42 provided with a curved recess 43 and having one end bifurcated for the reception of the bolt 40 and its other end provided with a bifurcation within which is pivoted a bolt 14 passing through the hole 39 and carrying nut 45.

The use of the device is as follows: In case the rear spindle of an automobile is broken so that a rear wheel becomes detached, the

"bar 10 is disposed beneath the rear axle housing A, the saddle members 242 and 3d en aging the underside of the housing. The clamping

members

30 and 42 are then swung down onto the saddle members and the bolts 27 and 4:0 swung into the bifurcations at the ends of the clamping members. The handled nuts 28 and 411 are then turned down to clamp the

members

30 and 42 against the housing A. It will be observed that the bolts 31 and MI permit adjustment of the clamping members30 and 12 toward or from the saddle members so that the curved recesses may receive housings of different diameters. The downward offset 11 in the bar 10 prorides for the accommodation of the flange B at'the end of the housing A. The clamping plates 21 are engaged upon the stub 17 and the bolt 23 tightened. The parts will then be arranged as shown in Figs. 1 and 2 and it will be readily apparent that the wheel 15 will take the place of the smashed ofi wheel so that the automobile may be towed or even driven to where the necessary repairs are to be made T In case a front wheel is smashed off, the

spindle or spindle body broken, or the front axle broken, the device is used as shown in Fig. 3. The bar is placed beneath the front axle with the axle clamped between the saddle members 24 and34 and the clamping

members

30 and 42, respectively. Instead of being engaged upon the stub 17, the plates 21 are, in this instance, swung upon their pivotal connection -with the rod 19 and clamped upon the steering arm connecting rod E. The wheel 15 will then take the place of the missing ordinary wheel and the auto mobile may be steered as usual, as the wheel 15 is carried by the movable spindle body and is moved in accordance with the rod F by virtue of the rod 19.

From the foregoing description and a study of the drawings it will'beapparent that I have thus provided an emergency axle carrying a wheel and adapted for engage-. ment upon either the front or rear axle of an. automobile to take the place of a missing wheel, the parts of the device being so constructed and arranged that the wheel maybe turned in steering or be held in straight position.

l' i hile I have shown and described the pre- I ferred embodiment of the invention, it will of course be understood that I reserve the right to make such changes in the form, construction, and arrangement of parts as will not depart from the spirit of the invention or the scope of the subj oined claims.

Having thus described my invention, I claim:
